Get behind Crocomire

From Glitches

From the game Super Metroid for the Super Nintendo

Do the Glitched up room / reset glitch and reset your game (after saving). Once you restart your game, you'll start from the beginning of the game with all your items. Shoot Crocomire with a charged Charge+Ice+Wave+Plasma shot. He will flash, and during this time you can jump and Morphball at the top of Crocomire and get behind him. This will make him go off the edge, killing him very quickly.
